They should be somewhat malleable or slightly soft. If they are hard, replace them. If useable clean them really good to take off any residue and put a light coat of clear silicone caulking on the half moon base. Do this a little before putting on the new valve cover gasket and valve cover. You want the silicone to be tacky.
When putting on a new valve cover gasket make sure the surfaces are scraped clean of any old gasket material. I thin film of grease or clean motor oil on both sides of the gasket will help keep it in place and also aid in sealing. Be careful to line up the valve cover so the gasket doesn't move.
I always keep a thin flat head screwdriver handy to tuck the gasket flush under the cover.

The most time consuming part will likely be carefully and thoroughly removing all traces of the old gasket material from both surfaces (cam cover and head). Best to also use new end plugs with the new gasket. Absent some obvious damage to the mating surfaces, no silicon or other sealer is needed on the new gasket. Installed dry, mine have stayed that way and do not leak. Others recommend grease, oil or chapstick on the new gasket before reinstalling.
Okay to use a small dab of silicon or other sealer around the end plugs before reinstalling the cam cover. FSM says 10-11.5 ft-lbs torque on the bolts. I just use a criss-cross pattern and get them barely snug. Remember the 2 spark plug wire clamps (if you use them).
While the cam cover is off, might want to also check the valve clearances (and make notes for future reference). Hopefully all will be within specs.
Also would be a good time to replace the rubber o-ring and seal in the tach pinion shaft holder if there's any oil seepage from that area.

Reborn and Patton,

No, you wouldn't want BLACK caps would you? That looks too stock, we need mods :sick: You can use the replacements or get nice stock black ones. A couple things I'd mention. If they are leaking, don't attempt to seal them with silicon or other sealer because they will begin leaking again in a short time. Another thing is you might not need to even replace your gasket. I can usually slide a thin feeler guage or similar between the gasket and the half moons to separare the two then just replace the rubbers. Clean good, then use Yamabond #4 gasket sealer on the new rubber and between the rubber and the original gasket and just reuse the old gasket unless it's broken from removing the cover. Unless someone used gasket sealer on the gasket (don't!!).

No. Then people wouldn't look at your bike and say "he has those cool billet cam caps"
